NGK ILKFR7A8 Laser Iridium Spark Plug – 90418
This NGK Laser Iridium spark plug is built for reliable ignition, clean combustion, and long service life. The fine iridium centre tip needs less voltage to spark, which helps cold starts and keeps performance consistent. A platinum pad on the ground electrode reduces wear, so gap growth is slower over time.
It suits many modern petrol engines, including turbo applications, where stable spark and heat control matter. Always use our vehicle lookup to confirm fitment for your engine.
- Designed for consistent ignition under load and at high temperatures
- Long-life precious metal construction helps maintain performance between services
